(BBC) - Fiat Chrysler has issued a safety recall affecting 1.4m in the US, after security researchers showed that one of its cars could be hacked.
On Tuesday, technology magazine Wired showed that hackers could take control of a Jeep Cherokee via its internet-connected entertainment system.
Chrysler said it was issuing a voluntary recall to update the software in affected vehicles.
The company added that hacking its vehicles was a "criminal action".
"The recall aligns with an ongoing software distribution that insulates connected vehicles from remote manipulation, which, if unauthorised, constitutes criminal action," the company said.
